Dr. Giovanni Vulpetti, a physicist based in Rome (Italy), has written many scientific papers about interstellar flight since 1974. He served as a chair of the Interstellar Space Exploration Committee, International Academy of Astronautics (IAA); as such, he arranged and acted as one of the coordinators of several IAA international symposia on interstellar flight. Since 1995, he has been an active member of the IAA committee for the Lunar Base (the return to the moon) and Mars exploration. This Lunar development international forum is chaired by Emeritus Professor H. H. Koelle, one of the main contributors to the Apollo project. Giovanni Vulpetti prepared a comprehensive overview of interstellar flight for the 1998 International Astronautical Congress and the September 1999 Journal of the British Interplanetary Society. He is particularly interested in fast solar sailing and in nuclear propulsion crewed mission identification and computation. In the 1990's, he found new types of sailcraft trajectories and published his results in Acta Astronautica. In 2001, he acted as consultant in a team to NASA/MSFC for studying original mission concepts - through fast solar sail trajectories - of the NASA Interstellar Probe. He is retired from Telespazio, where his primary work was on Earth satellites for scientific and environmental analysis. His current scientific interest is frontier mathematics.
